There are two issues that have prompted the filing of this STA .An adjacent operator is believed to be encroaching on the protected contour of W225CS .A period of silence is requested to facilitate preparation of measurements to support a legal challenge to the unauthorized operation .Secondly, A totally baseless claim has been made that W225CS did not receive written permission to rebroadcast the primary station . An action in state court for a declatratory judgment interpreting the parties agreement must be filed and W225CS does not desire to risk operating outside of fcc parameters .thus temporariy silent autnority not to exceed 180 days is requested
